kver {adehabitat} | R Documentation |
Objects of class kver
are created by getverticeshr
and
getverticesclusthr
: they contain the vertices of the home range
estimated using either nearest neighbour clustering or kernel
estimation. An object of class kver
is list of data frames of
class area
.
plot.kver
is used to display the home-range contours defined in
an object of clss kver
.
kver.rast
is used to rasterize the home ranges.
kver2shapefile
is used to convert the home ranges into a
shapefile object (for exportation to a GIS).
kver.rast(kv, asc) kver2shapefile(kv, which = names(kv)) ## S3 method for class 'kver': plot(x, which = names(x), colpol = rainbow(length(which)), colborder = rep("black", length(which)), lwd = 2, add = FALSE, ...)
kv,x |
an object of class kver |
asc |
a matrix of class asc |
which |
a vector of character indicating the polygons to be plotted |
colpol |
a vector of the color for filling the polygon. The default,
NA , is to leave polygons unfilled |
colborder |
a vector of the color to draw the border (black, by
default). Use border = NA to omit borders |
lwd |
the border width, a positive number |
add |
logical. If TRUE , the polygons are added to a
previous plot |
... |
additional arguments to be passed to the function
plot.area |
kver.rast
returns an object of class asc
.
kver2shapefile
returns a shapefile object (can be exported
using the function write.shapefile
of the package
shapefiles
.
kver2shapefile
requires the packages shapefiles
.
